Special Diet For Trees
Street trees in Hamburg, Germany, are now being fed with a solution of nitrogen, phosphorus, calcium and trace elements. This treatment became necessary because the older trees were unable to gain the proper amount of minerals from the ground during the last long winter. They absorbed melted snow which was mixed with melting salt and therefore contained too much sodium and chlorine. Some 100,000 trees in Hamburg showed the result of false nutrition. As the trees are not merely for decoration but highly important as the city dweller?’ “green lungs,” everything will be done to give the trees their proper diet Tests with the new method to fight tree illnesses were successful in Hamburg.
